Jamestown has proud military history, with monuments featured within the township. The Memorial Park features a restored 1907 Krupp SFH02 Cannon. It was captured in Palestine in November 1917 as part of the World War I campaign. In 1918 the Cannon was ceded to the 9th Australian Light Horse Regiment in the initial distribution of captured weapons.
